The device accordingto the invention con--- sists of apart l, called thesuction bell, which' is to be put over the nipple of a woman latellyconfinedand of the proper suction part2, both parts being connectedby altube 3v of flexible material for instance india rubber.V

is put in known manner with its large 'flat This part 1 consisting oftransparent glass,

the other part 7 ofthe suction bell the flexible tube 8 is arrangedandkept alsoiin its u e Y connected to the tube extending from the glasstube 9 which is enlarged at its endf-as shown by 10 in Fig. 2. On theother end of the enlarged part l0 an obliquely directed tube 5 is fixedwhich forms the mouth piece. In the interior of the `enlarged part 10 ashort tube 11 of small diameter is arranged which communicates with theytube 9 and which-is" provided with'an opening l2 atthe upper end. Inthe short tube 11 a valve 13 consist ing of a'short piece of glass isprovided which forms the suction valve.v The lower end of lower part ofthe short tube 1l. In order to llimit'the'upward movement of thevalvel2,

several. little projections 14k, are arranged.

this glass valve is pointedvand fits into the v If a suction' effect isexerted at the mouth i piece'the suction valve is lifted lwherebythemilk is sucked out of the nipple.A The' main Hobject` of the arrangementfof the-enlarged part l() -which-is not in communication with theflexible tube and of the short tube con nected with the'fiexible tubehavingan openi ing at .the upper end is to prevent the mix-v ture ofthespittle with the milk, an inconvenience which is avoided .by the presentinvention. v It is understood that the device may be of any othersuitablel material, which is vnot transparent, but care musty be takenthat @the suction device with the spittle collector and the arrangementof the suction valvel f V,must be as described in the description.
